6/12 INSTALLATION

6.2. WATER PIPING

When piping connections are performed:

1. Connect all pipes as close as possible to the unit, sothat disconnection can be easily performed whenrequired.

2. Connect the condenser and water coolers in thesame unit to the same common water piping.

3. It is recommended for the piping of the chilled waterinlet and outlet that flexible joints be utilised, so thatvibration will not transmit.

4. Whenever permissible, sluice valves should beutilized for water piping, in order to minimize flowresistance and to mantain sufficient water flow.

5. Proper inspection should be performed to check forleaking parts inside and outside the system, bycompletely opening the condenser and chilled waterinlet and outlet valves to the condenser and watercooler.Additionally, equip valves to the inlet and outletpiping.Equip an air purge cock and a drain cock onthe water piping. The cock handle should be removedso that the cock can not be opened under normalcircumstances. If this cock is opened duringoperation, trouble will occur due to water blow-off.

6. Sufficiently perform insulation to keep the chilledwater piping cool and to prevent sweating of thepiping.

7. Under the condition where the ambient temperatureis low in winter, there is a case where equipment andpiping will become damaged during the shutdownperiods at night, because the water in the pump orpiping will be frozen. To prevent freezing of the water,it is effective to operate the pumps even duringshutdown period.HITACHI Chiller has the pump ON/OFF operationcontrol (see Wiring Diagram) water from piping.Additionally, in a case where measures such as waterdraining are difficult, utlize antifreeze mixture ofethylene glycol type or propylenen glycol type.

8. The common water pipes (Inlet/Outlet of condenserand cooler, field supplied, should be connected tocondenser and cooler directly.

CAUTION:-Never use an antifreeze mixture of the salt type,

because it possesses strong corrosioncharacteristics, and water equipment will bedamaged

-This product is equipped with plate type heatexchangers. In the plate heat exchanger, waterflows through a narrow space between the plates.Therefore, there is a possibility that freezing mayoccur if foreign particles or dusts are clogged. Inorder to avoid this clogging, provide a. 20 meshwater strainer at the inlet of condenser and chilledwater piping near the product. A 20 mesh waterstrainer is available as an option.

NOTE:HITACHI chiller has the pump ON/OFF operation control (see wiring diagram)

CAUTION:In case of connecting some units to the samewater piping, design the water piping so that thewater distribution to each unit is equal (refer tofigure below) Imbalance of water distribution maycause a serious damage like a water freezing inthe heat-exchanger.

6.3. MINIMUM INTERNAL SYSTEM WATER VOLUME

To ensure the cooling operation at least 5 minuteswithout interruption, the internal chilled water volume inthe piping system should be greater than the minimumvolume as shown below.

NOTE:Minimum internal system water volume written belowis for standard ON/OFF differential, minimum internalsystem water volume shall be increased by thesetting of differential.

6.4. WATER CONTROL

CAUTION:When industrial water is applied for chilled waterand condenser water, industrial water rarelycauses deposits of scales or other foreignsubstances on equipment. However, well water orriver water may in most cases contain suspendedsolid matter, organic matter, and scales in greatquantities. Therefore, such water should besubjected to filtration or softening treatment withchemicals before application as chilled water.

It is also necessary to analyse the quality of water bychecking pH, electrical conductivity, ammonia ioncontent, sulphur content, and others, and to utiliseindustrial water only if problem is encountered throughthese check.

6.5.3. CAUTION ON USE HARC70-CE1 (OP)

Please use it correctly according to the following"CAUTION ON USE.”

As for the following:

“HARC” indicate “ HARC70-CE1” or“HARC70-CE1 OP”

“Monitoring Device “ indicate “ upper connectingdevice for supervise “, and “Control Panel” indicate“Control panel of Chiller unit”.

“SNVT” Indicate “Standard Network Variables Types”

1.Install HARC in a grounded metal box.

2.Install a short circuit breaker in the power supply ofHARC.

3.The transmission line between HARC and Chiller unitshould be “0.75mm2 twisted-Pair cable”. If it is notused, then it cannot communicate between HARC andChiller unit, and it does not work properly.

4.After an abnormal transmitting occurs between HARCand Chiller unit, and Chiller unit stops, in the case ofoperation starting by the hand operation, then onceturn off Chiller unit’s power supply, and turn on thepower supply. If it isn’t carried out, then Chiller unitkeeps the condition of transmission alarm.

5.After an abnormal transmitting occurs between HARCand Chiller unit, and Chiller unit stops, in the case ofoperation starting by Monitoring Device, then transmitan operation order after you transmit a stop orderonce. If it isn’t carried out, it can't start.

6.After Chiller unit, under control by HARC, is stoppedby the control panel, and operation is done from theMonitoring Device, then transmit an operation orderafter you transmit a stop order once. If it isn’t carriedout, it can’t start.

7.Don't set the setting temperature to Chiller unit, undercontrol by HARC, by the control panel. If it is done, thesetting temperature is changed. And, as for the settingtemperature, which changed in this case, transmit toMonitoring device.

8.After the setting temperature is changed by MonitoringDevice, in the case of turned off Chiller unit’s powersupply, set the setting temperature by Monitoringdevice again. If it isn’t carried out, then the settingtemperature becomes to the temperature by settingcontrol panel.

9.If power failure occurs in Chiller unit, under control byHARC, it may not revert to the condition before thepower failure. Try to detect that the operationcondition of Chiller unit changed, by the MonitoringDevice. If Chiller unit stopped due to the power failure,then transmit an operation order from the MonitoringDevice after the power supply restoration. And,transmit the setting temperature, mode from theMonitoring device. If it isn’t carried out, and thenChiller unit is stopping, and the setting temperature,mode is the initialisation value by Chiller unit.

10.When SNVT, which is transmitted from HARC, isused by other control device, premise that there istwo minutes delay between the transmitting SNVTand the movement Chiller unit . If it isn’t premised,then a problem may occurs in the control system.

11.Don't interrupt the power supply of HARC when youuse SCPT in HARC. Even if it exceedsMaxSendTime, when SNVT is not transmitted fromHARC, and SNVT is transmitted below with thesetting value of MinSendTime, then transmit SCPTagain . If it isn’t carried out, SCPT value continuesmaintaining “0”.

12.If the setting of control panel change Remote toLocally, and set Remote again, then set the settingtemperature and mode from the Monitoring Deviceagain. If it does not set, then the setting temperatureand mode continue maintaining the initialisation valueby Chiller unit.

13.When the abnormal transmitting occurs between theMonitoring Device and HARC, then the condition ofthe Monitoring Device may not correspond with thecondition of HARC. Set MaxSendTime and try thatthe condition of the Monitoring Device correspondswith the condition of HARC in the interval ofMaxSendTime .

14.It can't be used with the except for “ stop signal ofinput terminal of Chiller unit “.

7.1. PREPARATION

Tools and instrumentsHigh Pressure Compound Gauge. LowPressure Compound Gauge. Electrical Testerand General Tools.

CAUTION:- Switch On the main power switch, and energise the

oil heater for 12 hours before start-up, to sufficientlywarm the oil.

- Check to ensure that valves are correctly opened. Ifnot opened, serious damage will occur to thecompressor due to an abnormally high pressure.

- Remove the foreign particles and substances fromthe water piping without going through the watercoolers and condensers, and cleaning the waterstrainer filter before test runningg. Check to ensurethat no foreign particle and substance exists in thewater piping

7.2. TEST RUNNING

Test running should be performed as follows, when the unitis wired according to the HITACHI standard wiring label.

1. Switch ON the field-supplied pump and the coolingtower, and the pump and cooling tower will be startedimmediately. Check the condition and operation state ofthese components

2. Fully open the liquid line stop valve.

3. Set the operation switch to "ON", and the compressorwill be started in a few minutes after this operation,according to the following Operation Sequence Chart(Refer to pages 36 to 38).

Test running should be accomplished as follows.

CAUTION:

−When the unit is wired according to the HITACHIstandard wiring shown on the wiring label. Switch ONthe main power switch, and energize the oil heater for12 hours before start-up to sufficiently warm the oil.

−Each rotation direction of two rotors in the compressoris fixed so that a reversal phase protection device isequipped.

−However, the rotation direction should be checked witha following method:

−Confirm that phases R, S and T for the compressor iscorrectly connected. The correct phase connectioncan be checked by a phase sequence indicator. Ifnot, the compressor does not start due to activation ofthe reversal phase protection device.

- Cut the main switch and interchange two of threeterminals, R, S and T on the main terminals at the fieldconnection side in the unit.

1. Operate the pump for chilled water and otherauxiliary equipment such as fan coil units and airhandling units.Check to ensure that the chilled waterflows sufficiently and that other auxiliary equipmentoperate properly.

2. Set the switch at the desired temperature.

3. Depress the “ON“ push button, the compressor willbe started.

4. After system operation becomes stabilized, check thedischarge and suction pressures by 7-segment oncontrol panel.

5. Check to ensure that the thermostat functionsproperly.

6. Check to ensure that the control and protectivedevices function properly.

7. Starting timer and unload-starting timer are set at five(5), thirty (30) seconds, respectively, in accordancewith operation characteristics. Therefore, localadjustment should be avoided.

NOTE:- A loud sound occurs when this compressor is

stopped after the normal operation. However, thissound indicates no abnormalities and stops within afew seconds by the activation of the check valve.This sound is due to the reverse rotation of thescrew rotors, resulting from the pressure differencebetween the discharge and the suction pressure.

- Each compressor may show the different values ofrunning current due to individual capacity control foreach compressor. This is not abnormal.

7.3. INSTRUCTIONS AFTER TEST RUNNING

When the test running is completed, please instructcustomers about operation and periodic maintenancemethods before leaving the unit, by using Installation,Operation and Maintenance Manual. A special attention isrequired to the following caution:

CAUTION:-Do not cut off the power source switch during the

operating season. When the power source switch iscut off, the oil heater for screw compressor is notenergised, and the compressor might be damageddue to oil foaming at starting.

-When the operation season starts after longdisconnection of the power source switch, please turnon the power source switch 12 hours before startingoperation.

8.1. CONTROL SYSTEM

Electrical Operation Control advanced HITACHI WaterChillers are as follows.

Capacity Control

All models are equipped with an unloading system for eachcompressor, in order to adjust the cooling capacity and toprovide precise temperature control for the chilled water,coupled with electronic thermostats.

Control Panel

ON switch, OFF switch, Power Supply Lamp, OperationLamp, Alarm Lamp, Operation/Alarm Indicator for eachrefrigerant cycle and check switch are mounted in theControl Panel. The Control Panel is located at a positionwhere easy access is available. Operation/Alarm indicatorcan display individual alarm codes such as High-Cut, Low-Cut etc. this function is very useful for detecting what alarmhas occurred. Check switches are for checking chilledwater temperature and alarm occurrence data. Chilledwater temperature setting switches, ON/OFF DifferentialSetting Switches, Remote-Local Switch and so on arelocated at the rear side of Control Panel, in order not toaccess during operation.

Operation Hour-Meter

This hour-meter indicates the sum of the compressoroperation

Printed Circuit Board

A micro-processor, relays and electronic components aremounted on the Printed Circuit Board. Increased reliabilityis assured due to the elimination of mechanical parts andwires. This board contains various function by applyingmicro-processor as follows:

Screw Compressor Cycling Protection Circuit.The electronic timer of the screw compressor cyclingprotection (ccp) connected in the compressor control circuitdelays the screw compressor restarting period forapproximately three (3) minutes for No.1 compressor, four(4) minutes for No.2 compressor, five (5) minutes for No.3compressor.

Electronic Thermostat Circuit.The electronic thermostat senses chilled water outlettemperature, and operate capacity control solenoid valvesof HITACHI screw compressor.

Screw Compressor Reversing Protection Circuit.This circuit is composed of a reverse-phase protectiondevices, preventing reverse operation of the screwcompressor, because the screw compressor definitelycannot be operated in the wrong direction, due to themisconnection of the main power phases.

Restart after Short Period Power-Failure.In the case that a power failure shorter than 2 secondsoccurred, compressors can be restarted automaticallywithin 3 minutes after power supply.If power failure longer than 2 seconds occurres,compressor also can be restarted by selection switchsetting.

Power SupplyAll models need only single power supply . Control circuit ispowered from main power circuit. For remote control, pumpinterlock and pump operation, see the diagram of"Customer Wiring".

MAINTENANCE 11/39

11. MAINTENANCE

The unit should be periodically inspected according to thesame items as those described in the paragraph titled“Test Running“. In order to ensure dependableperformance and long life operation, the followingadditional items should be given for particular attention.

WARNING:If a fire accidentally occurs, turn OFF the main switchand use an extinguisher for an oil fire and an electricfire.Do not operate the unit near flammable gases suchlacquer, paint oil, etc. to avoid a fire or an explosion.Turn OFF the main switch when electrical box coversare removed for setting the temperature. Do notoperate the unit without fixing panels.

DANGER:Switch OFF main interruptor (MI) for any work insideelectrical box.

CAUTION:Perform periodical maintenance according to the“INSTRUCTIONS“ to maintain the unit in a goodcondition.Do not touch the parts at the discharge gas side byhand, since the pipes at the discharge side areheated by refrigerant and the temperature becomeshigher than 100 °C.Do not utilize this unit for cooling or heating ofdrinking water or food. Comply with local codes andregulations.Turn OFF all the main switches if refrigerant leakageor chilled / hot water leakage occurs. Also, if the unitcan not be stopped by the control switch, turn OFF allthe switches for power source.

11.1. COMPONENTS

Compressor

The semi-hermetic screw compressor requires periodicmaintenance, including replacement of parts. See theHITACHI Service Handbook for Screw Compressors, fordetails.

Electrical Equipment

Always pay careful attention to working voltage, amperageand phase balance. Check for faulty contact caused byloosened terminal connections, oxidised contacts, foreignmatter, and others.

Control and Protective Devices

Do not readjust the settings in the field unless the setting ismaintained at the point other than the point listed in thetable on chapter 11.

11.2. LUBRICATION

Compressor

The compressors are charged at the factory with thecorrect oil listed in “Component Data” and the compressornameplate. It is not necessary to add oil, if the refrigerantcycle remains sealed.

11.3. DEPOSITS

Slime and other minerals in the condenser water or chilledwater tend to deposit on inside surfaces of plates over along period of operation. As deposits of these mineralsincrease, excessive high discharge pressure or loweroperation pressure are detected, indicating evidence ofdeposits on the condenser or the water cooler. The figurein page 41 indicates the range where cleaning is required.

CAUTION:-Cleaning of plate type heat exchangers shall be

performed by specialists. Please contact yourcontractor or dealer of HITACHI.

-Clean the water strainer filter periodically according toits clogging degree. If not cleaned periodically, thewater strainer will be broken due to an excessivepressure to the strainer screen.

WARNING:-This product is equipped with plate type heat

exchangers. In the plate type heat exchanger, waterflows through a narrow space between plates.Therefore, there is a possibility that freezing mayoccur if foreign particles or dusts are clogged. Inorder to avoid this clogging, provide a 20 mesh water

strainer at the inlet of the chilled water piping near theproduct. If clogging in the plate type heat exchangeroccurs seriously, this will cause insufficient coolingperformance or local freezing in the plate type heatexchanger. It is strongly recommended that the heatexchanger be cleaned at the same time when thefilter is cleaned.

Pay attention to the following caution and normalcleaning method. For details, contact your Hitachiinstaller.

Water

Refrigerant

11/40 MAINTENANCE

CAUTION:-Correctly select cleaning agent depending on scales in

the plate type heat exchangers. The cleaningchemicals are different depending on fouling degree.

-This plate type heat exchanger is made of stainlesssteel. Do not use a cleaning agent containinghydrochloric acid or fluorine compound. If used, theheat exchanger will be damaged, resulting inrefrigerant leakage.

-After cleaning with cleaning agent, clean inside ofwater piping including the heat exchangers by usingclean water. Perform water treatment (preventivetreatment) in order to prevent the water circuit fromcorrosion or re-adhering of scales after cleaning.

-In the case that a cleaning agent is used adjustconcentration of the cleaning Agent, cleaning periodand temperature according to the scale degree.

-In the case that acid cleaning is performed,neutralisation treatment is required after cleaning.Treatment for neutralisation fluid should be performedby a waste fluid contractors.

-The cleaning agent and neutralizing agent are erosiveand stimulative against eyes, skin, mucous membraneetc. Therefore use protection tools (protection glasses,protection gloves, protection shoes, protection cloth,protection mask, etc.) in order not to absorb or touchthese agents during this cleaning work.

11.4. CLEANING METHOD

N° Name N° Name

1 Chiller Unit 5 Diluted Cleaning Fluid2 Chilled Water / Inlet Piping 6 Chilled Water / Outlet Piping3 Acid-resistant Type Water Pump 7 Cleaning Water Tank4 Hose 8 Waste Fluid Tank

1. Installation of Cleaning Circuit

-Stop the water Chiller unit.-Stop the circulating water pump.-Disconnect the connections at the chilled water inlet or

cooling water inlet and install a circulating water circuit byusing an acid-resistant type water pump.

2. Check of Circulating Circuit

Pour water in the cleaning tank and operate the acid-resistant type water pump.

-Check to ensure that no water leakage exists.-Check to ensure that the water hose is firmly fixed.-Check to ensure that the cleaning Agent will not damage

equipment near the water Chiller even if bubbles occurand touch them.-Check to ensure that good ventilation is available.-Check to ensure that no abnormal sound occurs.

3. Cleaning Work

-Discharge water in the water circuit of the air conditioningsystem.-Supply diluted cleaning fluid from the cleaning water tank

by operating the acid-resistant pump.-Circulate the cleaning fluid for an appropriate period of

time (the operating time should be determined accordingto the type of cleaning Agent, concentration and foulingdegree).

4. Waste Fluid

-Stop the acid-resistant pump.-Put the waste fluid into the waste fluid tank.-Supply water into the cleaning tank and operate the pump

for water cleaning.-Put the cleaning water into the waste fluid tank as same as

the waste fluid.-Measure pH degree by using a pH test sheet and

neutralize the waste fluid by gradually adding neutralizingagent.-After neutralization ask a waste fluid treatment contractors

to handle it.

5. Neutralisation Treatment in the Water Piping

-Put water into the cleaning tank.-Operate the acid-resistant pump after air-purging.-Measure the pH degree and gradually add neutralizing

agent until the pH reaches pH = 7.-Operate the pump for a specified period of time for

neutralization.-Discharge the used water.-Operate the circulating pump and clean the circuit with

water until no fouling fluid is observed.

6. Re-starting

-Reconnect the water piping as they were so that the waterChiller can operate.

-After cleaning, perform water treatment (preventivetreatment) in order to prevent the water circuit fromcorrosion.

MAINTENANCE 11/41

11.5. WINTER SHUTDOWN

When shutting down the unit for winter, clean the insideand outside of the cabinet, and dry the unit. Pump downthe refrigerant to the condenser and close the liquid outletstop valves. This unit should be covered during shutdown,in order to protect it from dust and environmentalconditions. Be sure to tighten the packing glands and thecap nuts of the valves.

Remove the drain plug and drain all residual water from thecondenser and water cooler piping systems, as such watermay freeze during the cold season. It is very helpful tosupply brine (anti-freezer) to the piping systems.

11.6. SPRING START-UP

After any extended shutdown period, prepare the unit foroperation as follows.

1. Thoroughly inspect and clean the unit.

2. Clean the water piping lines and the strainer.

3. Inspect the pump, the cooling tower and/or regulatingvalve.

4. Tighten all wiring connections and access panel.

CAUTION:When the main switch for this unit has been at theOFF position for an extended period of time, it shouldbe switched ON at least 12 hours before start-up, sothat oil in the compressor discharge casing may bewarmed enough, to prevent oil foaming by the oilheater during start-up.

11.7. PART REPLACEMENT

Replacement of parts should be undertaken by orderingfrom the HITACHI Spare Parts List. CAUTION:

Do not replace with spare parts which are not theequivalent.

11.8. REFRIGERATION CYCLE

Strainer

Check for clogging each time when the refrigeration cycleis opened.

Refrigerant Charge

Inspect the refrigerant charge of the system by checkingthe discharge and suction pressures. Perform a leakagetest, if any leakage is suspected, and always perform sucha test after a refrigeration cycle component is replaced.When refrigerant charge is required, follow the followinginstructions given for two cases:1. When Refrigerant Gas Completely Leaked.

Before charging the entire cycle must be completelyevacuated and dehydrated. A gauge manifold orequivalent piping preparation shown in the next page isrecommended as a convenient procedure regardingboth charging and evacuation.

Fully open all the stop valves.

Connect the evacuation line to the check joints of thehigh and the low pressure sides.

Completely evacuate the entire cycle with a vacuumpump.

Charge refrigerant to the refrigeration cycle byweighing the charging cylinder. The proper refrigerantcharge is listed on the nameplate.

When charging by weight is stopped due to highambient temperature, close the valve and operate theunit after circulating the chilled water through the watercooler.

2. When Only Additional Refrigerant is Required.Connect a gauge manifold to check joint of low pressureside, and connect a charge cylinder to gauge manifold.Operate the unit after circulating the chilled water.

Repeat the following procedure until pressure becomesproper (refer to page 46)

Charge the gas refrigerant a little slowly intorefrigeration cycle from check joint for low pressure.

Check the pressure after refrigeration cycle becomesstable.

NOTE:R407C shall be charged by LIQUID.

CAUTION:-Do not charge OXYGEN, ACETYLENE or other

flammable and poisonous gases into the refrigerationcycle when performing a leakage test or an airtighttest. These types of gases are extremely dangerous,because explosion can occur. It is recommended thatcompressed air or nitrogen be charged for thesetypes of tests.

-Mineral deposits on water cooler plates act as thermalinsulators, and also act as resistance Against waterflow, causing the water flow to decrease runningthrough them, and resulting in a decreasing of thecooling capacity. Deposits on the plates should beinspected at regular, intervals, experience with thewater Chiller will dictate accurate inspection intervals.

-These deposits should be removed by circulatingdiluted acid through the water passes after the waterhas been drained. As water in different localitiescontains different minerals, different acids arerequired, depending upon the thickness of thedeposits.

-This unit is equipped with an operation hour meter. Inthe case that the total operation time reaches 40,000hours or 5 years pass after installation, exchange thebearings of the compressor. For details, refer to theService Handbook for HITACHI Screw Compressors.

11.15. SERVICING FOR R407C REFRIGERANT SYSTEM

Refrigerant

This R407C refrigerant is HFC type so that it has a featureof no ozone depletion. If it is mixed with another refrigerant,the serious changing would occur on its character.Therefore notice the following point when handling thisrefrigerant.

Charge the refrigerant in LIQUID condition and NOT inGAS. As "R407C" is geotropic mixed refrigerant, if gascharging is performed, only the easy vaporisingrefrigerant would be charged into the system and thedifficult vaporising one would be remained in thecharge cylinder.

The cylinder, gauge equipped manifold and charge hoseare only used for R407C refrigerant.

Adjust the cylinder setting to charge in liquid.

Refrigerant Oil

UX300, which R407C refrigerant is easy to blend into it, isused for this system. The other oil is prohibited to use, sothat not to be mixed with another kind of oil at themaintenance and service work. This oil is very hygroscopic.Therefore minimum humidity handling is necessary.

Servicing Equipment

When servicing R407C system, servicing equipment suchas Charging Cylinder, Charging Hose, Vacuum Pump andso on, shall not be mixed with R22 equipment to avoidR407C composition change.

15.1. SELECTION EXAMPLE

1. Determine the system requirements

Condenser Water Inlet Temperature: 32 °CCondenser Water Outlet Temperature: 37 °CChilled Water Inlet Temperature: 12 °CChilled Water Outlet Temperature: 7 °CCooling Load: 300 kw

2. Select Model and Read the Performance

From the cooling capacity table,model RCUE100WG2 can beselected with the followingperformance.Cooling Capacity: 316.3 kWChilled Water Flow Rate: 54.4 m³/hWater Cooler Pressure Drop: 36.9 kPaCondenser Water Flow Rate: 68.7 m³/hCondenser Pressure Drop: 67.5 kPaCompressor Input Power: 83 kW

3. Correct the Data

1. Flow RateWhen the water Inlet/Outlet temperature difference isnot 5°C, correct the flow rate by the following formula:

5(°C) × Tabulated Flow Rate (CFR)CorrectedFlow Rate

=Given Temp. Difference(°C)

The corrected Flow Rate must be confirmed to be withinthe working range.

2. Cooling Capacity and Compressor Input.When the fouling factor is taken into consideration, thecooling capacity and the compressor input will bedifferent from the value indicated in the cooling capacitytable.

Corrected Capacity = Kfc × CAP

Corrected Input = Kfi × IPT

16.2. PART LOAD PERFORMANCE

The European Seasonal Energy Efficiency Ratio is a weighted formula enabling to take into account the variation of EER withthe load rate and the variation of water inlet condenser temperature.

ESEER = A . EER100 + B . EER75 + C . EER50 + D . EER25

With the following weighting coefficients:

A = 0.03

B = 0.33

C = 0.41

D = 0.23

The following part-load ratings shall be considered:

NOTE:

1.CAP: Cooling Capacity, IPT: Compressor Input

2.Capacity and Compressor Input show the percentageof the standard condition: Condenser Water Inlet /Outlet 30/35°c, Cooler.

3.Water Flow Rate and Pressure Drop can be calculatedby the Correction Factor Kf and Kp.

4.Example:

a)Model: RCUE120 WG2

b)Standard Condition: Capacity 388kW, CompressorInput 98.2kW

c)Outlet/Inlet Water Temperature -3/2°C, CondenserWater Outlet Temp. 30°C

- Ethylene glycol: 30%

- Capacity = 388*0.76=295 kW, Compressor Input =98.2*0.86=84.5 kW

- Water Flow(m³/h) = Kf*Capacity(kW)*0.86∆T(∆T=Inlet Temp.-Outlet Temp.)

= 1.037*295*0.86/(2-(-3))

= 52.6 m³/h

- Pressure Drop = Kp*Pressure Drop (water)

= 1.34*0.0188*52.61.897

= 46 kPa

where, Pressure Drop(water)= α x Qβ: see "WaterPressure Drop"
